Stress Concentrations in Bending
Inside this lesson
- Explain why geometric discontinuities raise local stress in bending
- Define the stress concentration factor K_t and use it with the net section
- Estimate K_t from typical geometric ratios for holes and fillets
- Apply σ_max = K_t · σ_nom to check critical sections
